well my battery is cooked due to the fact that voltage output is between 17/18v, so reg/rec's goosed. anyone know where i can get a new one?

is the 73a the same as the 76a with 3 yellow wires and a black and a red?
If so any with the same number of wires. Ie most suzuki's and alot of other manufacturers have 3 the same colour and a red and a black.
Only thing you might need to do is swap the connectors

yeah think so, just ordred one of the net for 80 quid from www.demonmx.co.uk. cheapest new ones of good quality i could find.

£80 should have converted it to one of the cbr6 F008 units, needs a slight rewire but megga mod.
